Abstract :
The optical amplification characteristics of a 0.781- mu m pumped thulium-doped fiber in the wavelength range of 1.6-1.7 mu m are discussed. A maximum net gain of 2.0 dB was obtained for 1.69- mu m operation. This optical fiber amplifier is suitable for in-service monitoring and identifying fibers operating at 1.2-1.6 mu m.<>
